since my original post i started to add more weight, and also mixed up my
exercise routine a bit more. i'm definitely feeling it the next day now. i still have to work push until i'm squeamish and sometimes dizzy, but not taking it too far or putting myself at risk.. i just come close to collapsing after working out. if that's what it takes then that's what i'll have to do. i also don't spend more than an hour at a time when i'm working out so i think i'm not overdoing it, just seems to take a lot to make an impact.
